To an wlwlnmay concern:

Be it known that l, Bonner E. L. JANNEY, a citizen of the United States, rcsir ling at Chicago, in the county of Cook and State of lllinois, have invented. iertain new and usefull Improvements in Pivot-Pin-Rctaining Means ior Car-Couplers, of which the follow{ ingis specification.

".iy invention relates to a device for hold iug n1 place a broken pivot-p1n in a car-coup-' er, and concerns more particularly such retautun means for a knuckle ivot- )in. Ha pin 01' this character is not provided with some sort of a device for maintaining its lower portion in place when the pin becomes broken, the coupler a whole becomes inoperative to perform its l'unctlon. To over come this defect, l have devised a simple means for holding the lower part of a-hroken pin in place, and if the upper portion of the pin has the usual head it will he maintained. in position by its head, while if it is headless the lower portion. of the broken pin will also support the upper portion in operative posi tion.

My means for holding the pin in place not only performs that function, but also acts as an indicator to disclose the condition of the, pin, which is necessarily more or less out 01, sight, and also prevents the pin from turning.

in the accompanying drawingslhave illustrated two embodiments of my invention,- wherein Fi ure 1 is a side elevation of a coupler the lmudide pivot-pin of which is equipped with one species of my novel retaining means. Fig. 2 ion fragmentary view of the under portion of the coupler-head looking upward;

Fig. 3 is a fragmentary elevation of the coupler-head'st right angles to the view of Fig. 1.. Figs. l and 5 are views similar to Figs. 2 and 3 of a modified form of my retaining means, end Fig. 6 is an elevation of the knuckle pivot-pin.

Referring to the drawings, the coupler has the usual shank 10 with the head. 11, the lat; ter being equipped with vertically-spaced ap-I; The knuckle 14 is ertured lugs 12 and 13. pivoted. on spin 15, which passes through the apertures of .lugs 12 and 13 and is supplied at its upper end withe head 16 and etits lower end, .L'higih projects a short distance helow the coupler-head, with a transverse round hole 17 Integral with the coupler-head, depend ing therefrom andi-id acent to the lower end of pivotpin is a lug 18, having a vertical slot 19 therethrough. Through the hole 17 and slot '19 is-adapted to pass a cotter-pin 20,

which fits in the hole 17 more or less tightly, but'loosely passes through the slot 19. When pivot-pin 15 is in its normal unbroken condition, the cotter-pin 20 is at the top portion of slot 19; but if the ivot-pin for any reason hecomes broken its ower portion drops a small amount, carrying with it the cotter 20 to the lower end of slot 19, the pin 20 performing 'the triple function of indicating the condition of pivot-pin. 15, retaining its lower broken portion in position to perform its function, and preventing rotation of" the pin. [in in specter examining these couplers will at once perceive that the knuckle-pin is broken when those of lug 18, but the use of two lugs makes :9. somewhat stronger construction. A

t Wlll be apparent that minor changes may be made 111 the device as described above without departing from the substance of the invention as defined bythe claims. For example, the lug 18 may have an open ture of approximately the size oi the cotton pin, while the pivot-sin 15 may be slotted,

the drop of the hroken lower portion of the latter :1- small amount indicating its broken cond tion, this portion of the pin being retained in operative position, however, by the cotter-pin.

I claim,

1. A car-coupler having 2 pivot-pin with a transverse hole therein, a slotted lug ad iaccnt to the hole in said pin, and acottcr-pin edspted to fit in the hole of said pin and in the slot Poi said lug to maintain said pivot-pin in place if it hecomes broken and by itsposition in the slot indicating the condition of the pivot-pin,

substantially as described.

2. A. oar-coupler having it pivot-pin with e transyersehole therein near its lower .end, a

slotted lug onwth e under side of the'head of said ear-coupler, a cotter-pin adapted to fig -in the hole of said pin and in the slot of sai lug to maintain said ivot-pin in place if it becomes broken and by its position in said slot indioatin the condition of said pin, substantially as esoribed. j r

3. A car-coupler havinga knuekle pivotgin, a lug on the lower portion of the coupleread, one of said parts having'aholetherein,

the other part havin a slotjan'd a cotter-pin adapted to fit in sai hole and slot tognaintain' said ivot-pin in place it' b'eeoines broken'an by its position in'said'sl'ot: indieating the condition of said knuckle pivotpin, substantially as described.

pm, a lug on the lower portion of the coupleread, one of said parts having a hole therein, the other part havim a slot, and a cotter-pin 4. A car-coupler having a knuckle piv0t-.

ada ted to iit in said hole and slot to maintain
